SC CT,long verification,wrong key wtf!?!?

[Beast1970]

Hello!I have 1 problem with SC CT.First ,its the image of the original game,and the serial
number is of course original.When I insert image in DT4 that verification goes for about 3
minutes(when is cheking is any optic drive connected) and after that I get the message that
cd key does not correspond with the disc(image) in the drive??WTF hows that?
Other games like TM SUNRISE,POP TTT,X3 works perfectly,but no,this one I cant start whatever I do..plz help?why does verification goes for couple minutes and with other SF games goes for 5 sec..helppp.

DVD ROM AND CDRW are disconnected..
